We heard late last month that the John Carmack-endorsed Oculus Rift VR headset would be hitting Kickstarter any day now, and it turns out today is that day. The project has just launched on the crowd-funding site with a goal of $250,000. To reach that, the team (led by company founder Palmer Lucky) is offering a variety pledge options, starting with posters and t-shirts for $15 and $25 (or $10 for a simple thanks), and of course the headset itself that is initially only being offered as a developer kit. It will set you back $300, which also includes a copy of Doom 3 BFG, and is expected to start shipping in December (signed kits and a complete bundle are available as well). Those that act fast can also snag one of 100 unassembled prototype kits, which run $275 and ship a month earlier in November. Despite that developer-only status, though, the project is already off to an impressive start -- it's raised over $50,000 as of this writing. You can find the usual video overview of the project after the break.

Update: The 100 prototype kits are now sold out, and the project itself has already sailed past the $100,000 $150,000 mark. John Carmack also clarified on Twitter that he's not "backing" the project in any official capacity, only endorsing it as a "wonderful advancement in VR tech."

Update 2: And the project has now easily met its goal on the first day. Those interested are still able to make a pledge any time over the next 30 days.
